Using Subs

A sub is the simplest way to reduce the size of the code, packaging method that appears in the Macro dialog box. Consequently, the one place where you always use a Sub is the main entry point for a program unless the program is a utility that you use only for programming purposes. A second way to use a Sub is to perform a task and not receive a direct return value. You can use a Sub to display an informational message. A Sub can modify information in several ways; it just cannot return a value. Only a function can return a value. You can, however, use arguments as a way to modify the information in a function by using a Sub. A second method relies on global variables. You can use the Sub as a way to break up large volumes of code. You can avoid creating a code that is written on many pages, and use Subs to break the code into smaller segments. This makes it easier for you and for another viewer to read the code.
